The hematopoietic supporting abilities are known to be impaired in marrow stromal layers developed from patients with acute myeloid leukemia (AML). In this study, fibroblast growth factor-4 (FGF-4), epidermal growth factor (EGF) or transforming growth factor-beta1 (TGF-beta1) were studied to see whether these growth factors can modify the functional development of leukemic stromal layers. Adherent stromal layers from 13 patients with AML and from six non-leukemic controls were established with 3ng/ml of FGF-4, EGF or TGF-beta1. Established stromal layers were washed three times and irradiated, followed by recharge of allogenic peripheral CD34 positive cells as an indicator of supportive function. Progenitor-outputs into supernatant were evaluated at biweekly interval with colony-forming assay until 6 weeks. The results showed that both leukemic and non-leukemic stromal cells established with FGF-4, but not with EGF, showed significantly higher progenitor cell-outputs compared with control stromal cells. By contrast, stromal cells developed with TGF-beta1 showed significantly lower progenitor cell-outputs compared with control. These differences were significant at later than 4 weeks after the recharge of indicator cells, suggesting that the stromal layer developed with EGF or TGF-beta1 preferentially affected the primitive progenitors rather than committed ones. These results indicate that FGF-4 and TGF-beta1 differentially affect the functional development of leukemic as well as of normal stromal layers.
